These are the safety bollards, and they can be found at bus stops. They have a strip of yellow retroreflective sheeting with black arrows at the top.

Their main function is to reduce the severity of the impact from errant vehicles. They also alert drivers to the presence of the bus stops, especially during nighttime, and thus protect the commuters at the bus stops.

Safety bollards are installed based on the posted speed limit of the roads on which the bus stops are located. Bus stops along roads with speed limits of 60 km/h and above require safety bollards.

Currently, 1,500 bus stops have been provided with safety bollards so far and the Land Transport Authority has plans to install them at about 400 bus stops by 2nd quarter 2008.
